I have a dependent binary outcome and 6 independent variables. These are measured in the same group of people at two moments in time in a descriptive longitudinal study. I am assessing whether these independent variables increase the likelihood of achieving the binary outcome. I know that I could do a logistic regression analysis of the results gathered at either one of those moments in time but I was wondering if there was an analysis I could perform that would incorporate both measurements of the same participants at those two points in time.
